Some performances end up as aberrations while others signal true change. Consider these from Sunday:

Tennessee Titans RB Chris Johnson (25 carries, 141 yards): Sell now. Johnson gained 45 yards on 33 carries in the three previous weeks combined. Last season, he had 12 games with 64 rushing yards or fewer and four games when he topped 100 yards. His previous game of more than 100 yards was followed by a 23-yard effort.

Buffalo Bills running backs (24 carries, 84 yards): The rushing attack against the New England Patriots involved Fred Jackson (13carries, 29 yards), C.J. Spiller (eight, 33), Tashard Choice (two, 14) and Johnny White (one, 8). Both healthy, Spiller and Jackson likely will ruin what could be a situation with one primary back. The Bills also are hitting a brutal stretch of the schedule with the next five games including four road trips vs. the San Francisco 49ers, Arizona Cardinals, Houston Texans and Patriots. Expect lower-level games from Jackson and Spiller for the next month or more.

Minnesota Vikings WR Jerome Simpson (seven targets): He completed his suspension for violating the NFL drug policy and played his first game as a Viking. Percy Harvin received eight passes as the primary target, but Simpson was thrown to seven times and caught four for 50 yards to lead the Vikings. Expect those stats to rise for at least the next two weeks when the Vikings host the Titans and travel to play the Washington Redskins.

Chargers QB Philip Rivers (35% of completions to wide receivers in four games): Compare this to tight ends (22%) and running backs (43%). If you want to know why Rivers averages 224.2 passing yards a game, this is it. There are no decent receivers going deep or capable of breaking off long gains.

Patriots RB Brandon Bolden (16 carries, 137 yards): There is no doubt that the rookie is the newest hot property on your league's waiver wire. But Bolden's big effort came against the Bills, after his first three weeks totaled seven carries for 15 yards. Sunday's output came during a game in which the Patriots won 52-28 and Stevan Ridley ran 22 times for 106 yards and two scores. Chances are high that you can never comfortably start Bolden, at least with Ridley and Danny Woodhead healthy.

Extra points

Hold off on reports of the fantasy demise of Michael Turner. The Atlanta Falcons running back busted out Sunday with 13 carries for 103 yards and a surprising three catches for 68 yards and a touchdown on five targets. Jacquizz Rodgers, meanwhile, had 10 touches but didn't do nearly as much, compiling 58 total yards.

The Texans' Arian Foster and Andre Johnson get all the fantasy headlines for Houston, but tight ends Owen Daniels and James Casey have quietly been snaring their share of fantasy points. In Sunday's 38-14 romp vs. the Titans, Daniels and Casey combined for 11 catches, 108 yards and two TDs, upping their combined season totals to 31 for 314 and a three scores. Daniels has been the more prolific of the duo with 19 catches, 232 yards and two TDs.

Kickers rarely are deserving of top fantasy billing, but St. Louis Rams rookie Greg Zuerlein should be starting in all leagues. After his 4-for-4 effort on field goals Sunday, which included 58- and 60-yarders, Zuerlein is 12-for-12 this season, with eight kicks coming from 40 yards or more.

Tennessee quarterback Jake Locker left Sunday's game in the first quarter after getting flattened by a Texans blitz. He separated his shoulder for the second time this season, though an MRI revealed no structural damage. Veteran Matt Hasselbeck mopped up, completing 17 of 25 passes for 193 yards and two TDs with two interceptions.

Green Bay Packers wide receiver Greg Jennings caught a 9-yard TD pass as his only reception before aggravating his groin injury Sunday against the New Orleans Saints. Three of Green Bay quarterback Aaron Rodgers' seven TD tosses this season have gone to No.3 wideout James Jones, who caught two Sunday.

Of the Saints' 75 offensive plays Sunday, only 19 were runs, with Darren Sproles, Pierre Thomas and Mark Ingram combining for 45 yards.
